Abstract

A fluid operated actuator (103) is provided that includes an actuator housing (104) and a piston assembly (109) including a piston (106) and a piston rod (108) movable within the actuator housing (104). The fluid operated actuator (103) further includes a plurality of detents (210) unified with the piston rod (108) and a lock (209) configured to move between a first and a second position. The lock engages the plurality of detents (210) when the lock (209) is in the first position or the second position to prevent the piston assembly (109) from moving with respect to the actuator housing (104). The lock further disengages from the plurality of detents (210) when the lock (209) is between the first and second positions to allow the piston assembly (109) to move with respect to the actuator housing (104).
